para el primer dibujo seria 1/12
para el segundo dibujo seria 1/16
para el tercer dibujo seria 1/10, pero tengo dudas con esta porque no se ve toda la figura.
Step-by-step explanation:
Answer: a) 30, b) 0.2138, c) 0.0820
Step-by-step explanation:
Since we have given that
X be the number of calls in 1 hour = 60 minutes
Rate of one call every two minutes.

(a) What is the expected number of 911 calls in one hour?

(b) What is the probability of three 911 calls in five minutes? If required, round your answer to four decimal places.

Number of calls = 3
So, P(X=3) is given by

(c) What is the probability of no 911 calls during a five-minute period? If required, round your answer to four decimal places.

Hence, a) 30, b) 0.2138, c) 0.0820
Hello from MrBillDoesMath!
Answer:
See Discussion section below
Discussion:
2x^2 + 5x + 3 = (2x+3)(x+1) which is Choice 3
3x^2+10x+4 =-1/3 (-3 x + sqrt(13) - 5) (3 x + sqrt(13) + 5)
I don't think any of the provided choices are right!
8x^2+10x-3 = (2x+3)(4x-1) which is Choice 2
6x^2-7x-4 = -1/24 (-12 x + sqrt(145) + 7) (12 x + sqrt(145) - 7)
I don't think any of the provided choices are right!
2x^2+x-28 = (2x-7)(x+4) which is Choice 2
Thank you,
MrB
0.985 is the median.
I hope this helped
